acanthocytosis

Definition

Noun: A medical condition characterized by the abnormal presence of acanthocytes in the bloodstream. Acanthocytes are red blood cells with a spiky, thorny appearance due to irregular projections from their surface.

Usage

This term is used exclusively in medical contexts to describe a specific hematological finding. It is often associated with underlying disorders affecting lipid metabolism or the structure of red blood cell membranes. - The patient's blood smear revealed acanthocytosis, prompting further investigation. - Acanthocytosis is a key diagnostic feature of abetalipoproteinemia.

Advanced Usage
  • As a diagnostic marker: The condition of acanthocytosis itself is not a disease but a sign of an underlying pathological state.
    • The neurologist noted that the acanthocytosis was consistent with the suspected diagnosis of chorea-acanthocytosis syndrome.
Variants and Related Words
  • Acanthocyte (noun): The individual abnormal red blood cell with spiny projections. This is the cell type whose presence defines the condition.
    • Under the microscope, the acanthocytes were clearly visible.
